About Backing Up the Model and References
Working with the Backup Model
If Preferences > Create Backup Models is selected from the Regeneration Manager, the regenerated backup model is used. A copy of the model is saved as regen_backup_model####.prt prior to each regeneration. After successful regeneration of the feature, the copy is removed.
Creating Backup References
Backup references are used to prevent feature failure when a reference model is not in session. When a backup reference is available you can highlight and dynamically preview a reference when the original is not present.
Some reference types, such as Direction References and Chains, are automatically backed up. You can create additional backup references from File > Options. Click Assembly and set the options under External Reference Control.
When the original reference is missing and a feature uses a backup reference:
The feature is regenerated with the backup references when possible and the backup reference is shown in the collector and can be highlighted.
Reference status is displayed in the collector and in the Troubleshooter dialog box.
Preview is available. You can choose to make changes and complete the feature using the backup reference or to cancel the tool.
When the original reference is missing and the feature has no backup reference:
The feature fails.
A missing reference is marked in the collector.
No preview is available.
You cannot resolve the failure until the reference is replaced, the original is found, or the feature is suppressed or deleted. Canceling the tool will not resolve the failure.
When the original reference has become invalid and the feature has no backup reference:
The feature fails.
The failed or invalid reference is marked in the collector.
No preview is available.
You cannot resolve the failure until the reference is replaced, or the feature is suppressed or deleted. Canceling the tool does not resolve the failure.
